He aha ka polyethylene chlorinated a me kona mau ʻano:

1. ʻO ka polyethylene chlorinated, i ʻike ʻia hoʻi ʻo CPE ma ka ʻōlelo Pelekania, he ʻano polyethylene ia. ʻO ka polyethylene chlorinated (CPE) kahi mea i loaʻa ma ka hoʻololi hapa ʻana i nā ʻātoma hydrogen ma ka polyethylene kiʻekiʻe-density (HDPE) me nā ʻātoma chlorine. ʻIke ʻia ka CPE ma ke ʻano he pauka keʻokeʻo, ʻaʻohe mea ʻawahia a ʻaʻohe ala.
2. ʻOi aku ka maikaʻi o ke kūpaʻa ʻana o ka polyethylene chlorinated i hana ʻia mai ka polyethylene haʻahaʻa haʻahaʻa HDPE i ka mahana kiʻekiʻe a me ka ʻelemakule wela ma mua o ka polyethylene chlorinated i hana ʻia mai ka polyethylene kiʻekiʻe. Ma ke ʻano laulā, hoʻohana pinepine ʻia ka polyethylene me ka density o 0.93-0.96g/cm3, ka awelika o ke kaumaha molekala o 50000 a 250000, a me ka helu hoʻoheheʻe ma waena o 0.01 a me 2.0g/10min e hana i ka polyethylene chlorinated. ʻO ke kekelē o ka chlorination o ka polyethylene chlorinated he hopena koʻikoʻi i kona mau waiwai. Ke emi ka nui o ka chlorine ma mua o 15%, he plastic ia; Ke 16-24% ka nui o ka chlorine, he elastomer thermoplastic ia; ʻO nā elastomers e like me ka rubber me ka nui o ka chlorine ma waena o 25-48%; Ke 49-58% ka nui o ka chlorine, he polymer paʻakikī semi elastic e like me ka ʻili; Ke hiki ka nui o ka chlorine i 73%, lilo ia i resin brittle. ʻO ka hoʻokomo ʻana i kahi 27% chlorine i loko o ka polyethylene kiʻekiʻe-kaomi e hoʻopau loa i ka crystallization, ʻoiai ʻo ka hoʻokomo ʻana i kahi 30% chlorine i loko o ka polyethylene haʻahaʻa-kaomi me ka crystallinity kiʻekiʻe e hoʻopau loa i ka crystallization. Ma ke ʻano he elastomer rubber, ʻoi aku ka maikaʻi o ka chlorine i loko o ka pae o 30-40%. I kēia manawa, ʻo ka nui o ka chlorine o ka rubber polyethylene chlorinated kalepa ma ka pae o 25-45%. Ke piʻi ka nui o ka chlorine, hoʻomaikaʻi ka pale ʻaila, ka hanu ʻana, a me ka pale ʻana i ka lapalapa; Ke emi ka nui o ka chlorine, ʻoi aku ka maikaʻi o ke kūpaʻa anu, ka resilience, a me ka hana kūlou compressive.
2. Nā ʻano o ka Chlorinated Polyethylene CPE
1) He laholio piha ʻo CPE me ke kūpaʻa maikaʻi loa i ka wela a me ka ʻelemakule oxygen, ke kūpaʻa ʻana i ka ʻelemakule ozone, ke kūpaʻa waikawa a me ka alkali, a me nā waiwai kemika.
2) He kūpaʻa maikaʻi loa ko CPE i ka ʻaila, me ke kūpaʻa maikaʻi loa i ka ʻaila ASTM 1 a me ka ʻaila ASTM 2, hoʻohālikelike ʻia me NBR; Kūʻē maikaʻi loa i ka ʻaila ASTM No. 3, ʻoi aku ka maikaʻi ma mua o CR a hoʻohālikelike ʻia me CSM.
3) Loaʻa i ka CPE ka chlorine element, nona nā waiwai pale ahi maikaʻi loa a he mau ʻano puhi a me ka anti dripping. Hiki ke hoʻohui ʻia me nā mea pale ahi i hoʻokumu ʻia i ka antimony, chlorinated paraffin, a me Al (OH) 3 i nā ʻāpana kūpono e loaʻa ai nā mea pale ahi me ka pale ahi maikaʻi loa a me ke kumukūʻai haʻahaʻa.
4) ʻAʻohe mea ʻawahia o ka CPE, ʻaʻohe ona metala kaumaha a me nā PAH, a hoʻokō piha i nā koi o ke kaiapuni.
5) Loaʻa i ka CPE ka hana hoʻopiha kiʻekiʻe a hiki ke hana i nā huahana e hoʻokō i nā koi hana like ʻole. Loaʻa i ka CPE ka hana hana maikaʻi, a he nui nā māka e koho ai me ka viscosity Mooney ma waena o 50-100.
